This suggests that temp3 is your CPU temperature, so you can add a
label for it in your configuration file.

It isn't clear what situations the 3 lines above correspond to.

Changing the sensor types is almost never needed, as the BIOS should
have set them up properly. I suggest you remove the configuration
statements

Despite the name, the TM and TM2 CPU feature flags have nothing to do
with hardware monitoring. They refer to the CPU's ability to
monitor and handle its own temperature automatically. Your CPU
certainly supports that anyway, it's not exactly a recent feature.

What really matters to us is the hardware monitoring chip used on the
board, and the kernel version you are running.

> Please, survey the added files.

Sorry but you got it wrong. Sending files as 7 separately tar-gzipped
archives is the best way to make sure nobody will look at them. If you
really must send many files then put them in a single archive. But the
best way is to not compress them and send them as plain text so that
readers can see them immediately. Just make sure you only include the
relevant information. If you don't know, don't include, and ask if we
need more.

But more importantly, you did not clearly state what problem you had. So
nobody is going to look into your files with no idea what they are
looking for. Remember, you are asking for help for free, so it's really
up to you to make it as easy as possible for us.
